Red Line (Massachusetts Bay Transportation Authority)
The Red Line is one of the four MBTA subway
lines in Boston. It has its northwestern terminus at the Alewife station near Fresh Pond in West Cambridge
, meets the Green Line at Park Street and the Orange Line at Downtown Crossing, and splits into two branches south of South Boston. One branch terminates at Braintree
, and the other at Ashmont with an extension to Mattapan.
The Red Line gets its name from crimson, the school color of Harvard University. Until the 1980s, when it was extended to Alewife, the Red Line used to terminate at Harvard Square.
